Physical Properties
- High modulus-to-density ratio, 3.8 times that of aluminum or steel, minimizes flexure and reduces the chance of mechanically induced failure.
- Thermal conductivity of approximately 210 W/m•K exceeds by about 25% that of common aluminum metal matrix composites such as Al 6061.
- The CTE of 13.9 ppm/K matches that of the ceramic chip carriers (alumina has CTE of ~8ppm/K) more closely than does aluminum, which has a CTE of 24ppm/K.
- The stiffness and low density of AlBeMet® are beneficial in aircraft, where high loads generated during tight maneuvering can cause flexure of circuit boards, and subsequent mechanical failure.

“We best avoid wars by taking even physical action to stop small ones.”
—Anthony, Sir Eden (1897–1977)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
